Respiratory failure & ventilation

A novel positive end-expiratory pressure titration using electrical impedance tomography in spontaneously breathing acute respiratory distress syndrome patients on mechanical ventilation: an observational study from the MaastrICCht cohort

J Clin Monit ComputPublished Observational study

Authors' conclusion

EIT-guided PEEP titration by the RPF approach is feasible and is linked to improved overall lung mechanics) during SMV using a threshold of approximately 5% CL.

Study context

Population
COVID-19 ARDS patients on spontaneous mechanical ventilation
Participants
25 patients
Exposure
Electrical impedance tomography (EIT)-guided positive end expiratory pressure (PEEP) at pre-defined thresholds vs baseline PEEP
Outcome
Feasibility of regional peak flow (RPF) by EIT for PEEP titration during spontaneous mechanical ventilation (SMV); clinical and mechanical outcomes at thresholds vs baseline PEEP
Methodological detailssingle EIT measurements, MaastrICCht cohort
  • Single EIT measurements
  • MaastrICCht cohort
